ONCE UPON A TIME · 02

Nineteen thousand watts, no limiter

Angel Moraes opened this room in 1998 on the Paradise Garage model: the sound system is the point, and everything else arranges itself around it. Two arsons and two sound systems later, that is still the deal. We wrote the whole history down — including the part nobody prints: the system in there now was custom-built by the man who owns the place.

  1. 1998Moraes opens 858 Sainte-Catherine Est. Three-foot walls, a dancefloor on shock absorbers.
  2. 2003–08Craig “Shorty” Bernabeu’s build: six fourteen-foot stacks, 19,000 watts, not a limiter in it.
  3. 2008Fire guts the venue. Those stacks don’t come back.
  4. 2009 –Tommy Piscardelli reopens with a system he custom-built himself, and has been rebuilding ever since.
